To a/ZZ whom it may concern:`

l Be it known that we, STEPHEN E. BURKE, residing at Edon, Williams county, and SoLoN W. BURKE, residing at Wauseon, in the county of Fulton, State ofV Ohio, citizens of the United States, have invented a new and useful Swivel 'for Windmills,` of which the following is a specification.

The invention relates to improvements in swivels for windmills. Y 4 The object of the lpresent invention is to improve the construction of swivels for windmills and to provide a simple," inexpensive,`

and'eiiicient one designed for use in connection with the pull-out wire of a windmill and the operating-wire of a lubricator and-adapted to receive the said wires and prevent the same from being twisted bythe rotation of the millhead.

parting from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of aportion of a windmill provided with a swivel constructed in accordance with this invention. Fig. 2 is an enlarged detail perspective view of the swivel. Fig. 3 is a plan view of the same, the wires being in section. Fig. 4 is a vertical sectional view of the swivel.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 and 2 designate upper and lower portions of an operating-wire, which extend downwardly from a lubricator 3 to the base of the A further object of the invention is to pro-` cup-shaped upper section.

tower 4 to enable the lubricator to be voperl ated at the ground or at any other convenient point. The lubricator 3, which may be of any desired construction, is connected with the bearings ofthe windmill by distributing-pipes of any desired construction; but as the lubricator and the windmilI do not constitute any portion of the present invention a detail dei scription of the same is unnecessary. The

upper and lower portions of the operatingwire are connected with sections 5 and' of a swivel which is hollow to provide a central opening for the pull-out wire 7 ofv'tlie windmill. The upper section. 5 ofv the swivel is cup-shaped and is provided atits bottom with Y `portion of the operating-wire of the lubricator has its lower end passed through the perforated ears of the upper section of the swivel from one side thereof-,and this end is then bent upwardly and twisted around the bodyportion of the wire at 10, forming an approximately triangular loop, as clearly illustrated in Fig. 2 of the drawings. A The pull-out wire7 passes through the swivel at 'one sideof the triangular loop; but either of the wires may be connected'with the swivel, as will be readily apparent.

The lower section of the swivel is approximately tubular, being provided with a vertical tubular portion having a horizontal ange 11 at its upper end to engage the inwardly-extending bottom or flange 12 of the The bore or opening 13 of the lower section is preferably flared, as shown, to permit the lower portions of the Wires of the windmill to diverge. The tubular portion of the lower section is provided at a point below the upper section with a perforation 14 for the reception of the lower portion of the lubricator-wire, and the opposite portion of the lower section is cut away at 15 to facilitate the attachment of the lower portion 2 of the lubricator-wire. The lower portion 2 of the lubricator-wire has its upper terminal passed through the perforation or aperture of the lower section of the swivel, and it is twisted around the body portion of the wire at 16, as clearly shown in Fig. 2 of the drawings.

The upper section'of the swivel is adapted to rotate on the lower section to permit the upper portion l of the operating-wire of the lubricator to rotate around the pull-out wire without causing the wires to become twisted. The swivel, which is located at a point beyond the movable parts of the windmill, is preferably arranged adjacent to the top of the tower; but it may be disposed at any convenient point.

i 'the windmill.

1` wires passing through it, said swivel being composed of sections provided with means' It will be seen that the swivel is exceedingly simple and inexpensive in construction,

that it is adapted to be readily applied to either the pull-out wire of a windmill or the 'operating-wire of 4a lubricator, and that it `will etfectually prevent such wires from be- V'coming twisted by the rotation of the head of l What we claim isf f l', Inadeviceot'theclassdescribed,the combination 'with a windmill having a pull-out wire, and a lubricator having an operatingwire, of a hollow swivel havlng one of vthe for the attachment of the other wire, the latter being arranged exteriorly of the swivel, and o'ne of the sections of the swivel being adapted to rotate on the other, whereby vthe wires are prevented from being twisted by the rotary movement of the head ot the windmill, substantially as described.

2. Tn a device of the class described,the combination of a windmill having a pull-out wire,

Able of rotation on each other and provided with means for the exterior attachment of the other wire, substantially as described.

3. A device of the class vdescribed comprising a hollow swivel having a central guideopening, and composed of a cup-shaped section provided in its bottom with an opening, and a substantially tubular section tted in the opening of thebottom of the cup-shaped section, and provided with a projecting flange engaging the said bottom, said sections being provided with exterior attachment portions and adapted to turn freely on each other, substantially as described.

4. In adevice of the class described the combination with two-wires, of a hollow swivel having an opening to permit one of the wires to pass centrally through it and forming a guide for the same, and composed of a cupshaped section having a central aperture and provided at opposite sides with perforated ears for the exterior attachment of a portion of the other wire, and a tubular section fitted in the aperture .of the'cup-shaped section, and having a iiange provided beyond the cupshaped section with a perforation for the exterior attachment of the other portion of the wire which is connected with the said ears, substantially as described.

5. A'device of the class described comprising a hollow swivel designed to receive and form a guide for a wire, and composed of a cup-shaped section having an opening, a'tubular section fitted in the opening and provided with means for engaging the cupshaped section, said tubular section being provided with a flaring bore, and having a perforation at one side and cut away at the opposite side, substantially as described.

In testimony that we claimthe foregoing as our own we have hereto aiiixed our signatures in the presence of two witnesses'.
